To (1i/ZZ wl/ot it may con/cern:

Be it known that I, JOHN GLASGOW SAN- DERSON, engineer, a citizen ofEngland, residing at Salford Iron Works, Manchester, in the county ofLancaster, England, have invented certain new and useful Improvements inAFabric-Printing Machines, (for which I have applied for a patent inGreatBritain, No. 12,074, dated May 27, 1902,) of which the following isa specification.

This invention relates to machines for printing fabrics of the kind inwhich the printingrollers are forced into and out of contact with thefabric at predetermined intervals while the fabric is being printed. Forthis purpose endless revolving chains are employed, these havingsuitable projections fixed at the required distances apart, so as to actas the measuring apparatus for regulating the intervals of contact ofthe printing-rollers. The chains can be lengthened or shortened, so asto obtain a great number of diversity of intervals or contact. As thechains travel the projections on them through suitable mechanism actuatean arrangement for throwinga clutch in and out of gear. When the clutchis thrown in gear, motion is given to cams having projections that forcethe printing-rollers out of contact with the fabric andhavingdepressions which allow the rollers to be forced back into contact withthe fabric by weights or springs or the like. Preferably the cam-shaftpasses through a tubular shaft carrying the main bowl of theprinting-machine, which shaft revolves in suitable bearings in the sideframes.

In the accompanying drawings, Figure 1 is an end elevation of afabric-printing machine having my improvements, while Fig. 2 is a sideelevation thereof, partly in section. Fig. 3 is a side elevation, andFig. 4 an end elevation, of the measuring apparatus.

Like letters denote like parts in the several views. Y

It will be seen from Fig. 2 that this machine has seven auxiliaryrollers, or nips, as they are called; ebut these form no part of theinvention and are here shown actuated by spiral springs; but the usualweights or levers will suffice. The five nips u1 un um uw uv arearranged for printing. The first nip uis used as a drag-roller and theseventh nip et as a driving-roller to insure constant and steadyrotationof the printing-machine bowl.

,The main driving-shaft of the machine a is journaled outside of themachine and is driven by any suitable power. (Not shown.)

TheAgear-wheel aI is keyed to the shaft an and has a long boss, aportion of which has a brass bushing in which is supported the end ofthe cam-shaft f, which revolves in the hollow shaft of theprinting-machine bowl supported in suitable bearings in the frame of themachine. The shaft feXtends through the machine and is keyed at itsopposite end to the gear-wheel d, as hereinafter referred to.' Theprinting-machine bowl is drivenby friction of the printing-rollers ornips u1, un, um, uw, and uv, and of the roller uw. The gear-wheel atldrives the printing-rollers ul, et, and um, the roller u, and the wheelb. The latter is keyed to the shaft c, which drives one member of theclutch e through the gears cI cu cUI cw. The other member drives thecam-shaft f through the gear-d.I du. The gear-wheel d alsodrives therollers uw and uv.

The clutch e is engaged and disengaged by movement of the lever s, whichis operated bythe vibrating frame and the measuring device. The lattercomprises two chains gl g, traveling on adjustable chain-wheels h h,respectively, on shaft km, which are driven from shaft cV by gear k1 ku.Thesev chains hang freely at their lower ends and carry suitable tappetsw at distances apart corresponding with the required distance betweenthe impressions of the printing-rollers. The tappets w engage withlever-arms Z l on shafts m1 m, respectively. Journaled supports orguides y are provided at that point where the tappets w encounter thelever-arms ZI and Z to hold the tappets up against the lever-arms. Thelatter have lever-arms oI oII for depressing the levers 101 pu,respectively, and thereby'tripping the vibrating frame q, as hereinafterdescribed.

The frame q consists of a flat bar connected at its upper end to thepitman r of the eccentric fr and is adapted to reciprocate in twoguideways. Near the center of the frame q is a slot through whichprojects the lug su ofthe link s, which is slidingly mounted IOC behindthe frame q and is `providedat its upper end with a slot in which isseated the lower arm of a bell-crank s. The other end of the bell-cranks has a pin connected thereto which rides in a peripheral groove in thejournal of one member of the clutch e.

Upon the outer face of the vibrating frame q are projections, one aboveand one below the slot, upon which are journaled the levers p1 and p".The levers pl and@Il are normally held in the position shown in Fig. 3by means of spiral springs. The lever pl has its outer arm extendingupwardly from its bearing and the lever p has its outer arm projectingdownwardly from its bearing.

vThe vibrating frame q is reciprocated in two guideways in front of thelink s1 by means of the pitman rl of the eccentric r, keyed on the shaftjl", which is driven from the shaft cv, through the gears c1", jl, j,andjm.

When a tappet on the chain gI encounters the lever ZI, the arm 0ldepresses the lever p1 against the force of the spiral spring behind it,and on the upward stroke of the frame Q the depressed lever p engageswith the lug s, which projects from the link sI through the slot in theframe q. The link s1 is therefore forced upward, and through thebell-crank s, to which it is connected, the clutch e is thrown intogear. Similarly, on the down- .ward stroke ofthe frame q the lever p,which is depressed as the tappet passes under the end of the lever l,encounters the lug s and throws the clutch out of gear. When the clutche is in gear, the cam-shaft fis set in motion through the gear dt d andthe cams ifI t tm V comeinto operation. In the machine here shown,designedfor printing shawls or the like, one pair of the cams forces thebodyprinting rollers out of contact and the other pair brings thecross-border-printing rollers into contact with the fabric beingprinted. When the cross border is completed, the same pair of camsforces this pair of rollers out of contact, the other pair of cams bringthe body-printing rollers into operation, and the lever p operates thebell-crank lever s to disengage the clutch e, thus bringing the cams torest, while the body-rollers continue their printing until the nexttappet causes the engagement of the clutch e.

It will be seen that for variation of the intervals of contact of therollers it is only necessary to change the length of chains or thedistance between the tappets thereon.

Having thus described the nature of this invention and the best means Iknow of carrying the same into practical effect, Iclaiml. A machine forprinting fabrics, comprising a two-membered clutch, one of the inembersof whichfis connected witha prime mover, a cam-shaft, gearing foroperating said camshaft and driven by the other member of said clutch,printing devices, mechanisms operated by the cam shaft forintermittently throwing the printing devices out of operathrowing theprinting devices out of operai tion, lever mechanisms for throwing thetwo clutch members into engagement, and means actuated by the primemover for operating said lever mechanisms at predetermined intervals forthe purpose specified.
